CIRCUIT-CONTROLLER.

Application filed October 24, 1910.

To all whom it may concern Be it known that I, FRANCIS R. Hc-Y'r, a cit en of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Circuit-Contr llers. of which the following is a speciiication.

Like parts are indicated by similar characters of reference throughout the several views.

The apparatus forming the subject matter hereotl is designed to alternately connect and disconnect with a main circuit a generator and a storage battery at predetermined intervals of operative time, regardless of the purpose for which the main circuit is employed.

The apparatus is herein described as orming a part of an automobile lighting system. in which the battery is charged from the magneto driven by the engine during 've periods of time that the engine is in ope ation until the battery has received its full charge.

Vhen the battery is fully charged the charging circuit is automatically disconnected. and the lights are operated upon the battery charge until the battery is exhausted. or nearly so, when the charging circuit will again be connected by the automatic action of the apparatus.

It is to be understood that the invention is not limited to electrical lighting systems as described herein, but is applicable to other systems in which an electric motor, or other electrically controlled or actuated mechanism may be substituted for the series of lights in the present system, or it may be employed in a system of house or car lighting, or in other analogous combinations.

It is well known that to attain the highest efficiency of a storage battery, it should in charging receive a full charge each time, but should never be over charged. Also that the discharge each time should be to the same extent, preferably to a degree equal to substantially ninety percent. of the preceding charge.

It is further conducive to the long life and efficiency of the battery to charge it at a constant rate of amperage over an extended period of time.

For convenience of illustration it is assumed that the battery with which the apparatus forming the subject matter hereof is to be used, has a maximum capacity of ninety ampere hours, of which sixty ampere hours is the working charge and discharge, towhich the normal working of the apparatus limits the battery, leaving thirty ampere hours as a surplus or emergency supply.

It is assumed that the capacity of the generator is nine amperes, of which one ampere is required for ignition purposes, and the light circuit when being operated requiring two and a half amperes. The battery is adapted to be charged at the rate of five and a half amperes per hour, thus consuming the remainder of the total out put of the generator, amounting to a total of nine amperes. The apparatus is designed, (as shown in the drawing) to 'make the charging period twelve hours, making the complete charge sixty six amperes, or approximately ten percent. greater than the corresponding discharge. When the battery is fully charged the apparatus automatically shifts the connections and the battery is discharged at the rate of two and a half amperes the amount required for the light circuit,-for a period of twenty four hours making sixty amperes discharge, which plus the battery losses equals the prior charge. It is to be understood that these capacities and amounts are merely arbitrary, assumed for the purpose of this description, and are not essential proportions, but that the capacities, rates and proportions may be varied to meet different conditions of service. 7

In constructing the apparatus there is employed a casing 1 adapted to be supported on the dash of the automobile or in other convenient location. In order that the device may present a pleasing appearance the front and sides of the case are preferably though not necessarily formed of glass as shown at 2 in Fig. 2, thereby exhibiting the operating parts. The back plate 3 of the casing and the frame member 1 adjacent to the front of the case constitute the supporting frame for the several moving parts. Adjacent to the lower portion of the case are two switch buttons or keys, the ignition key 5 which controls the spark coil circuit and thereby the ignition of the engine, and the key 6 here after referred to as the master key which controls the main circuit for whatever purpose it may be used, in this instance it is the lighting circuit in which are located the several lamps of the automobile. Below these keys are shown three additional switch keys or buttons 7, 8 and 9, which are individual light keys controlling the head, side and tail lights respectively. Supported in the frame of the structure is a clock work or time motor adapted to drive the revoluble main shaft 10 at a predetermined rate of speed. This actuating motor includes the escapement wheel 11 controlled by the escapement 12 from which projects the usual fork 13 engaging with the balance wheel 14 by which the escapement is regulated. The movement is transmitted through the gear train comprising the intermediate gears and pinions 15 to the final shaft 16 of the gear rain, from which the movement is transmitted as here after described to the revoluble main shaft 10 at a constant speed such as to cause one revolution of the main shaft in an operating period of twelve hours.

The driving connections of the main shaft are best shown in Fig. 10. The final shaft 16 carries at one end the actuating or motor spring 17 which is the general source of power. The particular spring time motor as shown is not essential to the proper working of the apparatus, but any suitable driving mechanism may be employed, which is adapted to cause the movement of the main shaft 10 at a constant predetermined rate of speed. Loosely journaled on the main shaft 10 are two gear pinions 18 and 19 having on their adjacent faces clutch teeth 20 adapted to inter engage with correspond ing clutch teeth on a sliding clutch member 21 located intermediate the gears 18 and 19. The clutch member 21 is engaged with the shaft 10 by a spline and groove connection whereby it may be moved laterally to engage either of the gears 18 or 19, thereby causing the main shaft 10 to rotate in unison with either of the said gears.

The final shaft 16 of the motor gear train carries the gear pinion 22 which meshes with the gear 18 driving said gear counter clockwise or as indicated by the arrow in Fig.

9. The gear 18 carries therewith a gear pini T AVAILABLE ion attached to the gear 18, which pin ion meshes with a gear 2- on a counter shaft 25. The counter shaft 25 carries adjacent to the opposite end a gear 26 meshing with an iller pinion 2'7 journaled on a bracket 27* carried by the supporting frame. The idler pinion 27 in turn meshes with the loose gear 19 on the main shaft 10, driving said gear clock ise or in a direction opposite the rotation of the gear 18.

Thus the gears 18 and 19 are rotated in opposite directions and b shifting the clutch member from engagement with one of said gears into engagement with the other the direction of rotation of the main shaft 10 may be reversed. The clutch memher 21 is normally engaged with the gear It is always so engagec during the discharging period of the battery, and also during such time as the ignition key may be in its operated position. during the charging period; that is when the engine is running, maintaining the lights andv char ing the battery at the same time. A spring 28 tends to osc llate the clutch lever pivoted to the lug 30, to move the clutch member 21 into engagement with the gear 18. There are two forces in addition to the spring 28 which under certain conditions act upon the clutch lever to shift the clutch into and out of engagement with the gear 19. These are the movement of the ignition key to off position or when the engine is at rest, providing the parts are in their charging positions which causes the clutch to engage said gear and second, the movement of the swinging arm and traveling gear hereafter described from charging to discharging position wiich in the event the clutch 2-1 has been previouslv shifted into engagement with the 19, by the operation of the ignition l-cev will cause the reversal of the clutch to engagement with the gear 18. The ignition key comprises an oscillatory stem carrying a segmental plate 32 having there in a concentric slot 33.

The ignition key is r volubly adjustable to three predetermined positions. First. the off position in which the spark coil circuit is broken and the engine is at rest; second, the intermediate or starting position in which the spark coil and ignition devices are connected in circuit with the battery; and third, the on or operated position in ch the sparli coil is brought in circuit with the magneto or generator. These different connections are made hy means of a cam carried hy the stem which in its different positions engages and operates plungers which in turn operate electric switches as shown in the diagrammatic view Fig. 20. Engaging in the concentric slot 33 of the segm ntal plate 32 is a stud 34: carried in a linl: 35, the opposite end of which is pivotally connected to the lever 36 pivoted to the main frame. At the right of the casing, (F there is journaled an upright shaft 37 having a lCCr: arm 38 to which is attached a reciprocating link attached at its opposite end to the lever 36. The relation of the parts is such that as the ignition key is moved to its off position or to the left as shown in Fig. 9, the stud 3st in the linl: 35 engages the end of the slot in the scgmental plate and the slight additional movement the plate 35? drawing the link to the left oscillates the lever 36 the motion being transmitted through the link 39 and rock rm 38 causes a partial rotation of the vertical shaft 37.

fit rapper end the vertical shaft 37 carries a ro arm l0, connected by a resilient connection or spring all with the extremity of the clutch lever 29. he spring 41 forming the flexible or resilient connec ti n of the reel: arm 40 and the clutch lever is possessed of sutlicient resistance to overcome the tension of the spring 28, and if the lever is free to m. ve the clutch 21 from its normal position into engagement with the gear 19, the partial rotation of the vertical shaft 37 due to the operation of the ignition lrev to oli position will oscillate the lever 29 to shift the clutch. However if the parts a in discharo' lg position the clutch lever will he locliel against oscillation, and the movement of the vertical shaft 37 and roclr arm l0 will he compensated for by the elasticity of the connecting spring l1, and the clutch will remain in engagement with the gear 13. Journaled in a suitable braclret :2 is a swinging arm l3 on which is journaled t traveling gear 4-4:. By the oscillation of t swinging arm l3 the traveling gear it is moved into and out of mesh with the master pinion 4 carried by the main shaft 10.

Carried hr the mai shaft 10 adjacent to the master pinion i3 is a revoluhle cam disk 46. Upon rear side the traveling gear at is provided with a rate iet wheel 4i? eni a spring pawl S which maintains operated position engagement with the master and prevents undue rotation thered on the rear side of the swing ing arm adapted to engage an incli d cam face on the clutch lever F29 and oscillate said lever to return the clutch 2-1 to normal or into engagement with the gear 18 if it has been moved therefrom. If the clutch lever has not been oscillated from normal position. the engagement of the roller 4:9 with the cam face 50, upon the swingi movement of the arm to discharging position, will loci: the lever 29 and clutch 21 in their normal positions. It is to he understood that during the discharging period of the battery. the traveling gear 4 1 is maintained in mesh with the master BESTAKZAMRBLE SOP pinion 45, and during the charging period the swinging arm 43 is in such position that the traveling gear 44 is disengaged from the master pinion 4L5. Carried by the swinging arm 43 is a shifting terminal or contact 51, connected directly with the lighting or main circuit, and also by a shunt circuit containing suitable resistance with the battery, as shown in the diagrammatic view Fig. 20, the said shunt circuit being the battery charging circuit. The movable contact member 51 is adapted to engage either one of two stationary contacts and thereby complete either one of two circuits according to the position of the swinging arm 43.

l hen the swinging arm is in its operated position, that is when in the discharging position with the traveling gear in mesh with the master pinion 45, the movable contact 51 engages with the stationary contact 52, which is connected directly to the battery. lVhen the traveling gear is disengaged from the master pinion 45, that is during the charging pe iod the movable contact is engaged with the stationary contact 53, which is connected with the magneto or generator. The relation of these contacts is clearly shown in detail in F 11, and by reference to the diagrammatic view Fig. .ZOthe connections will be made plain. The swinging arm 13 is oscillated from its disengaged position into its discharging position with the traveling gear $4: in mesh with the master pinion 45, against the tension of the retracting spring 5st, by the operation of the master light key in its movement toward on position.

The master light key comprises a revoluble shaft or stem adapted by its rotation to close an electric switch in the main or lighting circuit. The particular switch operating devices are not essential, but as shown com rise a cam member 56 carried by the shaft or stem and adapted when moved to on position to depress a plunger 56 which in turn flexes the switch blades to complete the circuit. This construction is clearly shown in the dia rammatic view Fig. 20. Secured to the key shaft are two parallel frame members 57 and 58, movable with the key shaft. Projecting intermediate the frame members 57 and 58, is a stationary eccentric cam member 59.

The master key construction is best shown in Figs. 7 to 12 inclusive. The frame members 57 and 53 are of similar shape and register with each other, except that one of the said members has formed integral therewith the cam 56. This cam 56 however might be otherwise carried by the key shaft. The frame members 57 and 58 are each provided with radial slots 60, the slots of the respective members being in registry. Slidingly mounted on two studs 61 projecting is out of regis from the frame member 58 is a sliding cam plate 62, having therein an angular slot 63, the arm 63* of which may be brought into re istry with the slots 60 of the members 57 and 58, by a sliding movement of the cam plate 62. The cam plate 62 is provided with two notches 6st engaged by a spring pawl 65 to retain the cam plate in its adjusted positions. Pivot-ally supported on a stud 66 which projects through the slot 63 of the cam plate and the slots 60 of both frame members is a pawl arm 67 carrying at its extremity a pivoted spring actuated pawl 68. The engagement of the pivotal stud 66 in the several slots 60 and 63 is such that when the cam plate is in such position, as in Fi 7 that the slot portion 63 with the slots 60 the transverse stud 66 a ill be held at the top or outermost port-i on of the frame slots 60. Upon the longitudinal movement f the cam plate the slot portion 63 is brought into registry with the frame slots 60 and the pivotal stud 66 and pawl arm 67 are allowed to drop downward to the inner ends of the registered slots as shown in Fig. a. In Fig. 3 the cam plate is shown as partially operated and the parts in position just before the pawl arm moves down the slots. In its downward or inward movement the stud 66 and pawl arm are assisted by a retracting spring 69 attached at one end to the stud 66 and at the other to oneof the studs 61. The pawl arm 67 is movable about its pivotal connection in the slots 60 and 63, against the tension of the retracting spring 70,

The move nent of the pawl arm in one direction is limited by the stop arm 71 with which the spring tends to hold the pawl arm in engagement, as shown in Fig. 7. The pawl 68 is movable about its pivotal connection with the pawl arm 67 against the tension of the spring 72, the movement of the pawl in one direction being limited by the engagement of a lug 7 3 with a shoulder on the pawl arm 67 as shown in the detail view Fig. 18.

Upon the rota ion of the master key to the right or off position, the pivotal stud 66 of the pawl arm 67 riding on the periphery of the stationary cam is elevated to the upper or outer ends of the slots 60 and 63, against the tension of the spring 69. As the master key approaches the limit of its stroke to the right or off position, the end of the sliding cam plate 62 contacts a portion 7% of the main frame and is arrested thereby, the frame members 57 and 58 continuing to move causes the cam plate 62 to be shifted in relation to the frame members 57--58, thereby moving the slot 63 of the cam plate out of registry with the frame slots 60 engaging the stud 66 of the pawl arm in the angular extremity of the slot 63, and maintaining the pawl arm in its ele- Vated position. Upon the rotation of the master key toward the left or toward on position, the pawl of the pawl arm 67 which is being held in elevated position by the sliding cam plate engages a stud in the lower portion of the swinging arm and moves the swinging arm toward the left causing the traveling gear iito engage with the ma r pinion and shifting the mov able contact to discharging position in engagement with the stationary contact 52. This movement of the swinging arm is against the tension of I 5 1-. The swinging arm is retained in its operated position by a latch bar 76 which ongages a stud 77 in the swinging arm.

The swinging arm as it is moved by the pawl 68, engages a pivoted lever 78, and oscillates said lever in unison with the swinging arm, against the tension of a spring 79. The lever 78 is connected by a link 80 with one end of a pivoted bell lever 81, the opposite end of which carries a lug 82. The oscillation of the lever 78 as the .vinging arm is moved by the master key, causes the bell lever 81 and lug S2 to be advanced to meet the approaching cam plate 62 of the master key. Before the master key has completed its movement the end of the sliding cam plate 62 engages the lug 82 of the bell lever 81, and as the master key continues to move, causes the sliding cam plate to be again shifted relative to the frame members 57 and 58, thereby bringing the slot portion 63 of the cam plate int-o registry with the slots of the frame members allowing the pawl arm 67 to drop under the influence of the spring 69, out of engagement "liill the stud 7 5 of the swinging arm. This operation is most clearly shown in Figs. 2, 3 and a In Fig. 1 the master key is shown in its normal or off position, with the swinging arm and connecting parts in charging positions. In Fig. 2 the master key has been moved to the point of engagement of the pawl 68 with the stud 75 of the swinging arm but the swinging arm has not yet been moved from its original position. In Fig. 3 the parts are shown partially operated, the stud 77 of the swinging arm is about to enter the recess of the latch bar 76, the lug 82 of the bell lever 81 is in engagement with the cam plate 62 and is shifting the cam plate by advancing to meet the frame members as the key is operated, the slots 63 of the cam plate being in partial registry with the slots 60 of the frame members, but the movement of the cam plate not having been sufficient to permit the drop of the pawl arm 67 which does not occur until the limit of the stroke has been reached and the stud 77 is en aged by the latch bar 76 and the slots 63 and 60 are in complete registry. In Fig. 4 the parts are shown in operated positions, the swinging arm being retained by the retracting spring the latch bar and the pawl arm withdrawn from engagement therewith. During the discharge period, that is while the traveling gear is engaged with the master pinion and the swinging arm is retained in its operated position by the latch bar 76, the master key may be operated to turn the lights on or off as many times as may be desired, the pawl arm being elevated by the stationary cam 59 upon each document to off position and depressed upon the engagement of the cam plate 6'3 with the lug 82 upon each movement to; on position, the movement being an idle one, the pawl having no work to perform, the only result of the movement being the operation of the electric switch. If the discharge period is terminated and the swinging arm returned to normal position during the time that the master key is in the on position, upon the return of the master key to the right or off position, the pawl 68 will engage the stud 7 5 of the swinging arm but will yield against the tension of the pawl spring 72 allowing the arm and pawl to pass the stud on the off stroke of the key.

It is to be understood that the swinging arm is not moved to discharging position every time that the master key is turned to on position although the swinging arm is in normal position with the stud 75 in the path of the pawl 68. The master key may be operated as frequently as desired during the time that the swinging arm 43 is in its normal or charging position with the traveling gear disengaged from the master pinion, but the swinging arm is operated only at the termination of the charging period or when the main shaft 10 has made a complete rotation and the master cam disk 46 has reached a predetermined position. At all other times the swinging arm is locked against movement by the locking of the latch bar 76. During such time as the swinging bar is locked against movement the engagement of the pawl 68 with the stud 75 of the swinging arm arrests the movement of the pawl and pawl arm 67 of the master key, while the frame portions of the key continue to move thereby placing the spring 70 extending between the pawl arm and key frame under tension. The tension of the retracting spring 7 O of the pawl arm is suflicient to overcome the tension of the retracting spring 54 of the swinging arm 43. If during the time the master key is in its operated or on position with the pawl 68 engaged with the stud of the swinging arm, and the retracting spring 7 0 under tension, the charging period should be terminated and the cam disk 46 reach a position whereby it will unlock the latch bar 76, to permit the raising thereof and the consequent release of the swinging arm, the pawl arm 67 through the influence of the spring 7 0 will at such time move the swinging arm against the tension of the spring 5% to discharge position or with the traveling gear in mesh with the master pinion. Thus if the master key is operated at the time the battery is fully charged the latch bar 76 will be unlocked and the swinging arm 43 will be operated synchronously with the operation of the master key. If however the charging period is not complete the operation of the master key places the pawl arm spring under tension and the swinging arm &3 is oscillated subsequent to the operation of the key upon the completion of the charging period through the influence of the retracting spring 70.

The lock mechanism by which the swinging arm 43 is locked in either its normal or operated positions and released to permit the movement thereof only at the termination of the charging or discharge period, comprises primarily a bell lever 83 having in one arm a stud 84 bearing upon the latch bar 7 6, and in the other arm a stud or roller 85 riding upon the concentric periphery of the cam disk 46. The periphery of the cam disk 4C6 has therein a depression 86. The relation of the bell lever 83, the latch bar 76 and the cam disk so are such thatso long as the stud or roller 85 rides upon the concentric periphery of the cam disk the stud St in the other arm of the bell lever will bear upon the latch bar and prevent the elevation thereof. The bell lever is further held in contact with the latch bar 76 by the spring 87 against the tension of which the latch bar is elevated to permit the operation of the swinging arm. However when the cam disk has made a complete rotation and the depression 86 of the cam disk has been brought in registry with the stud 85 of the bell lever 83, the bell lever is free to oscillate against the tension of the spring 87, thestud 85 passing into the depressed portion of the cam disk periphery, thereby permitting the latch bar to rise.

The latch bar is elevated by the action of the stud 77 of the swinging arm acting on the inclined cam face 88 of the latch bar as the swinging arm is forced over by the pawl arm 67 under the influence of the spring 70 which is strong enough to overcome the tension of both the spring 54 and the spring 87. The latch bar continues to raise and the swinging arm to move (toward the left in the drawings) until the stud 77 reaches the recess of the latch bar when the latch bar immediately engages the stud 77 of the swinging arm through the influence of the spring 87 and retains the swinging arm in its operated position. At this time the stud 85 of the bell lever again passes onto the concentric portion of the cam periphery and the latch bar is again locked, this time with the swinging arm in its operated position.

Connected with the supporting shaft of the bell lever 83, or otherwise movable with said bell lever is a rock arm 89 connected by a link 90 with a lever 91 pivotally. supported on a suitable bracket The lever 91 carries the transverse pin 9%, insulated from the supporting lever 91, which contacts and forms an electrical connection between the arm of the'circuit terminal 53 and a similar terminal arm 96 connected with the generator.

The construction is such that during the entire charging and discharging periods, while the stud 85 of the bell lever rides the concentric portion of the cam disk L6 and while the latch bar 76 is in normal position, the transverse pin 9% will contact the terminal arms 95 96 and complete the circuit. However upon the elev ion of the latch bar 7 6 to permit the shi ing of the swinging arm a3, and the consequent oscillation of the bell lever 83, the movement of the bell lever is transmitted to the lever 91, and the transverse pin 9 is lifted from the terminal arms 95 and 96, as shown in Fig. 8, thereby breaking the circuit at this point. On account of the difference in le :verage of the rock arm 89 and the arms of the lever 91, the movement is multiplied and the make and break connection of the transverse pin 94: and the arms and 96 is ac complished by a quick movement which reduces to minimum the tendency of the con tacts to arc at each operation. Immediately upon the return of the latch bar to normal the pin 9% likewise returns to contact with the terminal arms 96 and 95 where it is locked by the engagement of the stud 85 with the concentric portion of the'cam disk.

The several parts remain in their operated positions with the contact 51 engaging the terminal 52 and the traveling gear engaging the master pinion $5 in which positions they are retained by the engagement of the latch bar 76 over the stud 77 of the swinging arm throughout the discharge period as determined y one rotation of the traveling gear td. In the theoretical case stated as an example for which the device of the drawings is especially adapted, the discharge period would be twenty four operating hours, during which the battery would be discharged at the rate of two and a half amperes per hour making a total of sixty amperes the amount received by the battery in the previous char ing period of twelve hours at the rate of five amperes per hour. It is to be understood that the charging period and discharge period do not necessarily consist of twelve and twenty four. consecutive hours respectively, but maybe intermittent periods of operation to the total of twelve and twenty four hours respectively.

Considering the last named condition first tlie arrest of the motor at the end of the p riod. with particular reference to Jig. 1, it will be seen that the master key when tuned to oii position en ages and i lever 101 pivoted to the support- To the lever 101 is connected a cam face 88 of the latch bar 76 when the stud 81- of the said bell lever passes into the depression 86 of the cam disk.

force escapement wheel 11 to arrest the movement motor.

lVhen the hell lever 83 is oscillated under normal conditions by the elevation of the latch bar '70 to engage or release the swing ing arm the movement of the bell lever is not sufficient to cause the engagement of the detent with the escapement wheel. ll' hen however the bell lever is acting under the influence of the spring 104: the bell lever s oscillated to the extreme degree of movement the stud 85 of said bell lever entering a recess 80* at the bottom of the depression in the cam disk permits an additional movement of the bell lever sufiicient to force the detent 106 into engagement with the escapement wheel by the contact of the arm with said detent.

As a means of arresting the motor under the other condition mentioned, there is provided adjacent to the escapement a reciprocating plate 107 to which is pivoted a stop lever 108. The reciprocating plate 107 is adapted to be moved toward the escapement mnism or toward the left in the drawagainst the tension of a retracting ing by the en agement therewith of the winging arm %3 as it moves into discharge position. or by the oscillation of the pivoted lever 30 upon the movement of the ignition key to off position or toward the left in the drawing. The upper end of the stop lever 108 engages with a pin 109 projecting from the reciprocating bar 102 and through a slot in the supporting frame as shown by otted lines in the drawing, and thence into e p th of the stop lever. The lower end stop lever carries a stud adapted to engage a bifurcated arm 110 projecting from escapement wheel and thereby the age i a of the the escapement 12. If the reciprocating plate 107 is in its operated position, that 13 if moved toward the left in the drawing by the engagement therewith of the swinging arm 43 or the pivoted lever 36 (when the ignition key is off and the engine at rest) thestop lever will not engage the bifurcated.

'With the several parts in the positions key with the lever 101, the reciprocation of the plate 107 will therefore cause the stop lever to be oscillated, advancing the lower end into engagement with the bifurcated arm 110 and arresting the motor. If the ignition key is not turned to off position with the parts remaining as shown in Fig, 1,'which shows the lever 101, the bar 102 and bell lever 103 operated and the spring 104 under tension, the motor will be arrested at the completion of the rotation of the shaft 10 which will bring the depression 86 of the cam disk to a point to be entered by the stud 8st of the bell lever 83, and the motor will be arrested by the action of the detent 106.

' Each time that the swinging arm is operated to discharge position, it engages and shifts the plate 107 in the same manner that V the plate is shifted by the lever 36. However in as much as the swinging arm is moved to discharge position only by the operation of the master key to on position, the tension on'the lever 101, the bar 102, the bell lever 103 and the spring 104 will be relaxed and the pin 109 will have been moved away from the stop lever 108, and the movement of the plate will only carry the stop lever with it and will not cause the oscillation of the stop lever to cause its engagement with the bifurcated arm 110. However if after the swinging arm has been moved to discharge position and has served to shift the reciprocating plate 107, the master key be then turned to 05 position its engagement with the lever 101 will reciprocate the bar 102 to cause the pin 109 to engage and oscillate the stop lever to cause it in turn to engage the bifurcated arm 110 and arrest the motor during such time as the lights may remain turned off. The adjustment of the arm 110 and the detent 106 is such that the balance I wheel is each time arrested at the limit of its stroke, in order that upon its release the motor will again resume operation.

Electrical cz'rcm'ts.-The various circuits and electrical connections are illustrated on Sheet 10. Referring to the diagrammatic view Fig. 20, a represents the generator or magneto adapted to synchronously charge the storage battery 6, and supply the main circuit 0, until the battery has received a full' charge, after which the circuit 0 is supplied by the battery alone until the battery charge is exhausted. The main circuit as shown in'the drawings is a lighting circuit containing the head lights 0 the side lights 0 and tail light a and is controlled directly by the master key 6. by which the generator at is driven is controlled through the ignition circuit d with its spark coil (Z and spark plug (Z by the ignition key 5 as hereafter described.

Leading from the positive side of the generator a is a line a? connecting with the spring arm 96 connected by the transverse pin 94. with the corresponding spring arm 95 which in reality is a portion of the stationary terminal 53. See Fig. 11. From the stationary terminal 52 a line a leads directly to the positive side of the storage battery 6. Oscillating between, and alternately engaging the stationary terminals 52 and 53, is the movable contact 51 connected by the line a with the positive side of the switch 0 From the opposite side of the switch 0 is a line a connecting with the line a leading to the negative side of the gen- The engine erator. The storage battery 0 is bridged 96, the transverse pin 94, the arm 95 to the stationary terminal 58, thence through the movable contact 51 to the line a the current dividing and a portion passing through the connection 6 and resistance 0 into the battery I). lhe resistance 6 is such that the battery receives a constant supply and the line a will continue to carry sufficient current to supply the lights 0 c and 0 or such other electrical apparatus as may be connected in the main circuit. The current continuing past the connection 6 through the line a connects through the positive side of the switch 0 with the main circuit 0, when said switch is operated by the move ment of the master key 6 as shown in the drawing, and passing through the main circuit and the negative side of the switch thence through the line a to which is attached the negative connection 6 of the battery, the current returns to the negative side of the generator through the line (L5, thus completing the circuit from the generator through the lights and through the battery.

When the battery has received a full charge the movable contact 51 is shifted by the mechanism before described whereby the contact 51 is connected with the stationary terminal 52, thereby disconnecting the generator from the circuit by the breaking of the contact between the movable contact 51 and terminal 53. The shifting of the movable contact while disconnecting the generator connects the battery 6 in series with the main circuit and lights. During the time the movable contact is in its operated position as shown by dotted lines or as before named the discharge period, the current passes from the positive side of the battery 5 through the line a to the stationary terminal thence through the movable contact 51 and line a to the switch 0 through the positive side of the switch to the main circuit 0, thence through the negative side of the switch and the line a as far as its connection with the line b which completes the circuit to the negative side of the battery. It is to be understood that when the master key 6 is in off position the switch 0 is open and main or lighting circuit is disconnected from the generator and battery circuits. However when the contact is in charging position, in engagement with the terminal 53, as shown in the drawing,

the generator will continue to charge the battery 5, even though the switch 0 is open. In this event the entire current passes through the line a the connection If and resistance 72 to the battery, thence through the line 6 line a? and line a to the negative side of the generator. The ignition circuit of the driving engine is adapted to be supplied rst from the battery until the engine and generator are in running order, after which the ignition circuit is supplied by the gen erator.

The ignition key 5 assumes three diiferent positions. In its cit posi ion the connection of the ignition circuit (Z with both the generator and battery is open or broken at the switches (Z and (3 as shown in the drawith the ignition circuit open, the enthe same condition, that is with the engine and generator at rest during the charging period, as shown in the drawing, it may be desired to operate the lights, for instance while the automobile is stationary on the street. In this case, without providing a shunt for removing the resistance .71 from the circuit, the light would burn but dimly, the current therefor passing from the battery through the resistance. To overcome this ditliculty there is provided a shunt circuit comprising the line 6 leading from the positive side of the battery to the switch 5 which is closed at all times when the ignition key is in ofi position, and the ignition circuits therefore open and the generator at rest thence from the switch Z) through he line Z) to the connection 5 at the opposite side of the resistance 5 The main circuit is therefore supplied from the battery through said shunt circuit to the line a and around the resistance 2) thence through the line 0, to the main circuit 0 and returning through theline 2 as before.

hen moved from off position to its first operative position, the ignition key 5 closes the switch (Z which connects the battery through the line I) and connection (Z with the line (Z forming one side of the ignition circuit, the current passing through the coil (Z and for a short distance through the line a to the line a thence through the line b to the negative side of the battery. This ignition circuit from the battery is used for starting the engine and generator, after which the ignition key 5 is again shifted to its extreme on position in which it closes the switch (Z and at the same time opens the switch 6 The closing of the switch (Z connects the line (Z leading from the positive side of the cnerator a with the line d, by means of the connection (Z The ignition current passing from the generator through the line (Z the switch (Z connection (Z and line (Z to the coil (Z returns through the line a to the negative side of the generator, thus completing the ignition circuit.

It will be noted that in the drawing each of the individual lamp circuits, 0 c and 0* are provided with resistance, of c and 0 brought into circuit by the switches 7, 8 and 9 when the lamps are cut out, whereby the main circuit always consumes the same amount of current regardless of the number of lights used. This li hting circuit howveris merely incidental and not essential to the working of the apparatus. It is to be understood that other electrically operated or controlled apparatus may be substituted for the lamps shown in the drawing. So long as the main circuit consumes current at the same rate each time the master key is operated, it isimmaterial for what purpose the current 18 used.

The operation.lt will be assumed that at the middle of the charging period the engine is at rest, the lights turned oil, that is both the ignition and master keys in oli' position, and the battery partially charged,

' which is the condition shown by the relation of the parts in Fig. 7. It will be seen that under these conditions the time motor is held inoperative by the engagement of the stop lever 108 with the bifurcated arm 110. In order to start the engine and therewith the generator, the ignition key 5 is turned to its intermediate position which closes the switch (Z connecting the ignition circuit (Z with the battery Z) through the lines 5 and 6*. The initial movement of the ignition key releases the tension on the lever allowing said lever to be retracted by the spring 36*. Upon the withdrawal of the lever 36 the shifting plate 107 is retracted by i s spring 107*, which withdraws the stop lever 108 from engagement with the arm 110 and releases the time motor which resumes its-operation. The ignition switch is then shifted to its extreme position which connects the ignition circuit 62 with the generator through the switch (Z and the lines (Z and a The time motor rotates the main shaft 10 and therewith the master cam 16 at a constant rate of speed until the recess 86 of said cam is entered by the stud or roll '85, at which time the battery has received its full charge. If the master key 6 is in off position, (as shown in Figs. 1, 7 and 8) at the end oi the charging period, the bell lever 103 is held in operated position by the bar 102 and lever 101, and the spring 104: is under tension tending to oscillate the bell lever 83 to its extreme limit of movement which it does when the stud or roll 85 enters the notch 86 in the master cam. This extreme movement of the bell lever 83 under the influence of the spring 10 2 causes the arm 105 to operate the detent 106 to arrest the time-motor, and at the same time operates tarough the arm 89 and link 90 to lift the arm 91 and break the connection of the generator with the battery by removing the transverse pin 94: "from engagement with the springs arms 95 and 96. Fig. 8 shows the several parts under such condition, that is' when the end of the charging period has been reached during the time that the main circuit is disconnected by the master key being in of? position. The time motor is shown locked by the detent 106 and the contact 94, 95 and 96 broken. If however before the end of the charging period is reached, that is it before the stud or roll 85 enters the recess 86, the master key is operated to on position, the pawl 68 will engage the stud 75 of the swinging arm and as the master key continues to move the spring actuating the pawl arm 67 is placed under tension, and the parts assume the positions shown in Fig. 2. In this position the bell lever 103, the bar 102 and lever 101 have returned to normal position as shown in Fig. 6, and the tension on the spring 104. is relieved, and the bell lever 83 is influenced only by the spring 87 which tends to hold the latch bar 76 down where it is locked by the bell lever 83, until the end of the charging period when the stud or roll 85 enters the recess 86, which allows the bell lever 83 to oscillate against the tension of the spring 87. The pawl 68 bearing on the stud under the influence of the spring 70 tends to move the swinging arm to shift the contact 51. The stud 77 hearing on the inclined face 88 of the latch bar tends to lift the bar, but is prevented fro doing so until the stud of the bell lever 83 enters the recess 86, whereupon the latch is free to rise, and the pawl arm 67 shifts the swinging arm against the tension of the spring In Fig. 2 the parts .are shown with the pawl arm under tension ready to shift the swinging arm and contact at the end of the charging period when the stud 85 of the bell lever enters the recess 86/ In Fig. 3 the parts are shown partially operated, and in Figs. l and 6 the operation has been completed.

This movement of the swinging arm disconnects the generator and supplies the main circuit solely from the battery through the line a and terminal lhe movement of the swinging arm also brings into mesh the traveling gear which serves to measure the discharge period and to release the swinging arm and contact when the gear has made a complete revolution. Fig. 6 shows the parts :during the discharge period. Each time the master key 6 is turned to oii position thereby disconnecting the main circuit the stop lever 108 is operated by the pin 109, bar 102 and lever 101 as shown in dotted lines, to arrest the time motor. Each time the master key is operated to on position the time motor is released. T he time motor therefore is in operation only during the time current is being used, and is inoperative at other imes and operates to rotate the traveling gear to register only the actual operating time. "When the gear a l has completed its rotation it releases the swinging arm by means of the lifting bar 97 and the arm is returned to normal by the spring 54.

If during the charging period the ignition key is turned oii during the time that the master key is also off and the circuit disconnected, as shown in Fig. 7 the lever 36 will engage and shift the shifting plate 107' to cause the stop lever 10 to engage the arm 110 and arrest the time motor. The reversal of the ignition key to on position will permit the release of. the motor (see Fig. 1) whereby the motor will again resume operation. Thus the motor is operated only when the generator is operated during the charg-
